The public once relied on passwords as their prime security tool, but are now accustomed to using their thumbprint to pay for their shopping or faces to be allowed through airport security as if it is the norm. Researchers at the USA’s University of Buffalo have gone one step further in the quest for total biometric identification – the use of heart dimensions. The team has developed a computer security system using the dimensions of a heart as an identifier. The system uses low-level Doppler radar to measure the heart, and continually monitors it to ensure no one else has stepped in to run the user’s computer.
